3000 Series Gateways & Media Servers
2.2 Chassis
The device's chassis is comprised of a compact, rugged 19-inch rack mount unit, 2U high
(3.5" or 89 mm), designed to meet NEBS Level 3 requirements. The device is a four-slot
chassis (four front and four rear slots) for housing the cPCI blades, and Alarm and Status
blades. The front and rear blades interface via a midplane located in the middle of the
chassis. The device's modular design allows easy installment and replacement of modules
such as the Fan Tray and Power Entry modules.
The chassis includes an ID Prom component that clearly defines the hardware version. The
chassis also includes a DIP switch for configuring the shelf geographical addressing.
2.2.1 Dimensions
The device's chassis dimensions are listed in the table below.
Table 2-4: Chassis Dimensions
Dimension Value
Width 48.3 cm (19 inches)
Height 2U or 8.9 cm (3.5 inches)
Depth 29.68 cm (11.69 inch)
Weight (fully loaded) 13 kg (29 lb)
Weight (fully loaded in packaging) Approx. 16 kg (35.5 lb)
2.2.2 Card Cage and Slot Assignment
The chassis contains four front and rear card slot cages. Blades and RTMs are inserted
from the front and the back and engage the midplane on either side, inside the card cage.
A diagram indicating the number of the slots and Power Supply unit is located on the Fan
Tray panel (refer to ''Chassis Cooling System'' on page 36). The midplane contains slot
keys (located in the middle of the midplane), which match the appropriate blade/RTM. This
prevents insertion of a blade/RTM in an incorrect slot.
Notes:
•While the slot keys on the midplane are designed to prevent the insertion
of a blade in an incorrect location, ensure that you don’t force a
blade/RTM into a slot to avoid damaging either the blade/RTM or the
midplane.
•High Availability (HA) is applicable only to Mediant 3000 (i.e., not
supported for IPmedia 3000 systems).
•All unoccupied slots are covered with protective blank panels (refer to
''Replacing Blades'' on page 62).
•The default IP addresses of the 8410 and 6310 blades depends on the
slot in which they reside: Slot #1 is 11.3.9.1 (active blade); Slot #3 is
11.3.9.2 (redundant blade). The subnet address for both blades is
255.255.255.252.

2.2.3 Alarm LEDs and ACO Button
Fault detection severity alarm LEDs and an Alarm Cut-Off (ACO) button are located on the
Fan Tray module (refer to the figure below), which is housed in the chassis' front panel.
Figure 2-5: Fan Tray Unit with Alarm LEDs and ACO Button
The ACO button is used to mute the external Telco alarm relay devices attached to the
Power Entry Module (refer to ''Power Entry Module (PEM/DC/3K)'' on page 38). When the
ACO button is activated (by being pressed), all alarm relays are returned to normal
position, de-activating the alarm relay devices. The chassis LEDs and other device alarm
signals are not affected.
The fault detection alarm LEDs (described in the table below) are connected to the Alarm
and Status blade.

2.3 6310 Blade
The 6310 blade is a member of AudioCodes’ 6310 series TrunkPack cPCI VoP
communication platform. The blade is a high-density, hot-swappable, cPCI resource blade
(form factor 6U PICMG 2.16) with a capacity of up to 2,016 DS0 channels, supporting all
necessary functions for voice, data, and fax streaming over IP networks. The blade is
considered a complete gateway / media server module. The blade occupies one slot of a
cPCI chassis, and features its own MAC and IP address. In addition, the blade provides
automatic protection switching (APS) capability (1+1) for STM-1/OC-3 PSTN interfaces.
The blade is housed in the chassis' front-panel slot, providing an RS-232 port, a reset
button, and various LEDs.
Figure 2-6: 6310 Blade
The blade is supplied with a rear input/output (I/O) module referred to as the Rear
Transition Module (RTM). The RTM-6310 provides the I/O connections to the supported
interfaces: IP, and one STM-1/OC-3 or three T3 PSTN interfaces. For a detailed
description of the RTM-6310, refer to ''RTM-6310 Rear Transition Module'' on page 24.
For Mediant 3000 systems, the blade is designed for protection capabilities. The redundant
RTM (RTM-6310 Redundant), housed in the rear panel, provides 6310 blade redundancy
protection by routing all calls between the active blade (previously redundant) and the
RTM. The RTM-6310 Redundant itself does not provide any PSTN ports. For a detailed
description of the RTM-6310 Redundant, refer to ''RTM-6310 Redundancy Rear Transition
Module'' on page 26.
Notes:
•PSTN APS is partially compliant to GR-253 only.
•The 6310 blade supports either STM-1/OC-3 or T3 PSTN interface,
depending on software configuration (using the PSTNTransmissionType
ini file parameter).
•HA (i.e., blade protection) is applicable only to Mediant 3000 systems.
